Castilla–La Mancha is an autonomous community of Spain that is divided into five provinces and 919 municipalities.
The ayuntamiento is composed of the mayor (Spanish: alcalde), the deputy mayors (tenientes de alcalde) and the plenary assembly (pleno) of councillors (concejales).
[9] Elections in municipalities with more than 250 inhabitants are carried out following a proportional representation system with closed lists,[8] whilst those with a population lower than 250 use a block plurality voting system with open lists.
[11] Many ayuntamientos also have a local governing board (Spanish: junta de gobierno local), which is named by the mayor from amongst the councillors and is required for municipalities of more than 5,000 inhabitants.
[6] The board, whose role is to assist the mayor between meetings of the plenary assembly, may not include more than one third of the councillors.
